I suspect you want to turn on a LIGHT in your room from your alarm clock so you can wake up in the morning..... RIGHT? I did that to my alarm clock but i didn't connect to the speaker wires. I connected a small 5 volt relay to the inside of the alarm clock to the same 2 wires that power the FM radio section. When the alarm clock turns on the FM radio, it activates the 5volt coil on the RELAY. Then I connected a 110 volt outlet onto my radio so i could plug in a desklamp. Now when the alarm clock comes on... so does the LIGHT. ANOTHER way to do that would be to just buy a programmable timer that plugs into the outlet.. Then set it to go off a few minutes before your radio in the morning.
